The present invention relates to a spacer 101 for forming a spacing between glass panes 201, 203, with a top part 103 and a lower metal foil 105, the two parts introduces an overlap 209, 211 parallel to the sidewalls of the spacer. By having overlapping regions at the side walls the spacer is stiffened and thereby spacers can be produced of quite thin material e.g. only thin metal foil.

1. A spacer (101) configured to attach to a first glass pane (201) and a second glass pane (203), respectively, of an insulating glass unit to form a spacing between the first glass pane (201) and the second glass pane (203), wherein the spacer (101) comprises a top part (103) and a lower metal foil (105),wherein the top part (103) has an inner wall part (107) with overlap surfaces (111, 109) at each end for connecting to said metal foil (105),wherein the metal foil (105) has an outer wall part (113) and two lateral sidewalls (115, 117) extending from the outer wall part (113), and towards the top part (103),wherein each end of the lateral side walls (115, 117) comprises an overlap surface (119, 121) parallel to each overlap surface (109, 111) of the top part (103),wherein the overlap surfaces (111, 119, 109, 121) are substantially parallel to the lateral sidewalls (115, 117) of the metal foil (105),wherein an end of an overlap surface (111, 119, 109, 121) overlapping another overlap surface (111, 119, 109, 121) is present at the outer surface on each side of the spacer (101), andwherein the overlap surfaces (119, 111) are overlapping in an overlapping area (209, 211) in the top part of the spacer (101) for mutual fastening in a region closer to the inner wall part (107) than the outer wall part (113),wherein the sidewalls (115, 117) of the spacer (101) are further configured to be connected to the first panes (201) and the second pane (203), respectively by a fastening material (205, 207) positioned below the overlapping area (209, 211), andwherein the overlap surfaces (111, 119, 109, 121) in the overlap area (209, 211) are spot welded or glued to one another, from an outer side of the overlap surfaces (111, 119, 109, 121). 2. A spacer according to claim 1, wherein the top part (103) further comprises a second overlap surface (110, 112) at each end, whereby the overlap surfaces (119, 121) at each end of the sidewalls (115, 117) of the metal foil (105) are mutually fastened between the second overlap surface (110, 112) and the overlap surfaces (111, 109) at each end of the inner wall part (107). 3. A spacer according to claim 1, wherein the lower metal part (105) and the top part (103) of the spacer further each comprises overlap surfaces (301, 303, 305, 307) being substantially parallel to the inner wall part (107) of the top part (103). 4. A spacer according to claim 1, wherein the top part (103) is made of metal foil. 5. A spacer according to claim 1, wherein the top part (103) is made of a plastic material. 6. A method of producing a spacer (101) configured to attach to a first glass pane (201) and a second glass pane (203), respectively, of an insulating glass unit to form a spacing between the first glass pane (201) and the second glass pane (203), comprising the steps of: providing an elongated top part (103) having overlap surfaces (109, 111) at each end for connecting to a metal foil (105);providing a metal foil (105) with two lateral sidewalls (115, 117) having overlap surfaces (119, 121); andattaching the metal foil (105) and the top part (103) to each other in such a way that the overlap surfaces (109, 111) at each end of the top part (103) and the overlap surfaces (119, 121) of the lateral sidewalls (115, 117) of the metal foil (105) are overlapping, and mutually fastening the overlap surfaces (111, 119, 109, 121) by spot welding or gluing from an outer side of the overlap surfaces (111, 119, 109, 121), wherein an end of an overlap surface (111, 119, 109, 121) overlapping another overlap surface is present at the outer surface on each side of the spacer (101). 7. A insulating glass unit comprising a first glass pane (201), a second glass pane (203), and a spacer (101) as claimed in claim 1.
